Opis:
Solid electrolytes based on sodium cryolite are present in aluminium electrolysers as frozen crystals formed on the side walls of the carbon lining (side ledge). Their main task is to protect the lining from the effect of liquid electrolyte and ensure temperature stabilization during the process of electrolysis. On the other hand, being electrically conductive, they can reduce current efficiency. In this study, the value of the electronic component of the total conductivity of the solidified electrolytes of different compositions was determined. It was found that the highest electronic conductivity is exhibited by electrolytes containing both aluminium and calcium fluoride. However, the electronic component of the total conductivity is not high, as it only reaches 0.1–2.3 mS/cm. Its share in the total conductivity of the solid multi-component electrolytes varies and, depending on their composition, is within a range of 1–10%.
Stałe elektrolity na bazie kriolitu sodowego są obecne w elektrolizerach do produkcji aluminium jako wykrystalizowane na bocznych ścianach wyłożeniach węglowego garnisaże. Ich głównym zadaniem jest ochrona węglowego wyłożenia przed działaniem ciekłego elektrolitu i stabilizacja temperatury procesu elektrolizy. Z drugiej strony mogą być przyczyną spadku wydajności prądowej, gdyż przewodzą prąd elektryczny. W pracy wyznaczono wielkość składowej elektronowej całkowitego przewodnictwa zakrzepłych elektrolitów o różnym składzie. Stwierdzono, że najwyższe przewodnictwo elektronowe wykazują elektrolity zawierające jednocześnie fluorek glinu i wapnia. Składowa elektronowa całkowitego przewodnictwa nie jest jednak wysoka i osiąga wartości rzędu 0,1–2,3 mS/cm. Jej udział w całkowitym przewodnictwie stałych elektrolitów wieloskładnikowych waha się, w zależności od ich składów, od 1 do 10%.

Opis:
Electrochemical processes take place in a metal object immersed into sea water even if an anticorrosive coating is applied [1]. As a result, flowing field appears around the object. There are naval mines between many other objects situated in the sea. Naval mines can be put in the seabed in order to be more difficult to detect by sonars. Such a mine is located on the line demarking two environments of different electrical conductivity. The results of a computer analysis of the influence of seabed’s electrical conductivity on the electric field’s disposition around a mine model are shown below. Also, a naval mine detection system based on the FPGA circuit is presented.

Opis:
In this study the results of simultaneous measurements of dynamic viscosity, thermal conductivity, electrical conductivity and pH of two nanofluids, i.e., thermal oil/Al2O3 and thermal oil/TiO2 are presented. Thermal oil is selected as a base liquid because of possible application in ORC systems as an intermediate heating agent. Nanoparticles were tested at the concentration of 0.1%, 1%, and 5% by weight within temperature range from 20°C to 60°C. Measurement devices were carefully calibrated by comparison obtained results for pure base liquid (thermal oil) with manufacturer’s data. The results obtained for tested nanofluids were compared with predictions made by use of existing models for liquid/solid particles mixtures.

Opis:
The suitability of a new wireless smart farming system for controlling irrigation and fertilization of horticultural plants was assessed in the study. The system (name: AGREUS® ) includes sensors (soil moisture, salinity, weather data), executive modules (valve modules), and an application available on the web portal (accessed through computers and mobile devices). The studies were performed under laboratory and field conditions. Laboratory tests included appraisal of the precision of soil moisture and salinity measurements carried out with the soil probe (comparison with the results obtained by laboratory methods). Operational tests were conducted in field trials. In these trials, assessment of the possibility of practical control of irrigation and monitoring soil salinity was performed in an apple orchard. The conducted analyses have shown the usefulness of the system, not only for automatic control of irrigation but also for making decisions about the necessity to fertilize plants. The system enables continuous monitoring of changes in soil moisture and salinity, including the migration of minerals across the soil profile (using a probe with several measuring elements) as a result of the applied irrigation or rainfall. The system allows for automatic application of irrigation or fertigation depending on the adopted soil moisture and salinity thresholds. However, the tests showed that a salinity index calculated by the system does not directly correspond to the salinity values determined by laboratory methods. For this reason individual interpretation and determination of optimal ranges for plants is required.

Opis:
In this paper, polypyrrole coated conductive fabrics were prepared using pyrrole as the monomer, p-toluene sulfonic acid as the doping agent and ammonium persulfate as the oxidant, adopting the simple method of situ polymerization of the liquid phase. Six types of conductive polypyrrole coated fabrics were prepared adopting polyester-cotton blended fabrics, nylon fabrics, wool fabrics, silk fabrics, basalt fabrics and aramid fabric respectively as base materials and using the same process conditions; its electrical conductivity was compared, and the distribution and resistance of the washing fastness of polypyrrole on the surface of those fabrics were studied. Results showed that under the same process conditions, the conductivity of polypyrrole coated terylene fabrics was the best, followed by the polypyrrole coated nylon fabrics and polypyrrole coated wool fabrics. Observed by electron microscope, the distribution of polypyrrole was more homogeneous on different base cloths. After washing, it was concluded that the combination fastness of polypyrrole with polyester-cotton, nylon and wool was better, while the combination fastness of polypyrrole with basalt and aramid was poor.

Opis:
The aim of this work is the development of Cu-Al2O3 composites of copper Cu-ETP matrix composite materials reinforced by 20 and 30 vol.% Al2O3 particles and study of some chosen physical properties. Squeeze casting technique of porous compacts with liquid copper was applied at the pressure of 110 MPa. Introduction of alumina particles into copper matrix affected on the significant increase of hardness and in the case of Cu-30 vol. % of alumina particles to 128 HBW. Electrical resistivity was strongly affected by the ceramic alumina particles and addition of 20 vol. % of particles caused diminishing of electrical conductivity to 20 S/m (34.5% IACS). Thermal conductivity tests were performed applying two methods and it was ascertained that this parameter strongly depends on the ceramic particles content, diminishing it to 100 Wm-1K-1 for the composite material containing 30 vol.% of ceramic particles comparing to 400 Wm-1K-1 for the unreinforced copper. Microstructural analysis was carried out using SEM microscopy and indicates that Al2O3 particles are homogeneously distributed in the copper matrix. EDS analysis shows remains of silicon on the surface of ceramic particles after binding agent used during preparation of ceramic preforms.

Opis:
Technologia wytwarzania masy szklanej jest wieloetapowym procesem obejmującym: sporządzenie zestawu, topienie, klarowanie i ujednorodnianie stopu oraz formowanie. Aby zestaw surowcowy został przekształcony w jednolitą, klarowną masę, muszą w nim zajść przemiany fizyczne i chemiczne, często wyhamowywane przez niewystarczający kontakt pomiędzy poszczególnymi ziarnami w zestawie surowcowym. Pojawiająca się w pierwszym etapie topienia zestawu surowcowego ciekła faza amorficzna, ułatwia lepszy kontakt pomiędzy nimi, dzięki łączeniu ziaren cienkimi mostkami. W pracy zbadano wpływ stopnia zagęszczenia zestawu surowcowego na szybkość reakcji oraz ilość tworzącej się fazy amorficznej. W tym celu komercyjny zestaw surowcowy na szkło opakowaniowe zagęszczono przy trzech różnych ciśnieniach: 0,2 MPa, 15 MPa oraz 40 MPa, a następnie przeprowadzono proces wygrzewania w temperaturach: 800°C, 1100°C oraz 1200°C.
The manufacturing technology of glass is a multi-step process comprising: preparing a set, melting, refining and homogenizing of the alloy and molding. In order to convert a batch of raw material into a unified, clear mass, chemical and physical changes must take place. These changes are insufficient contact between individual grains in set of raw materials. Liquid amorphous phase appearing in the first stage of melting raw mix, by combining grains with thin webs, facilitates better contact between them. The paper presents the effect of the degree of compaction of raw mix on the reaction rate and the amount of amorphous phase forming. For this purpose, a commercial batch of raw materials was compacted at three different pressures: 0,2 MPa, 15 MPa and 40 MPa, followed by annealing process at temperatures: 800°C, 1100°C and 1200°C.

Opis:
The study investigates the effect of heat treatment on the microstructure evolution and properties of an age-hardened Cu-3Ti-2Mg alloy. The precipitated Cu2Mg and β'-Cu4Ti phases consequently yield a depletion of the Cu matrix in regards to Ti and Mg solutes, which enhances the electrical conductivity. The Cu2Mg Laves phase and β'-Cu4Ti phase precipitates increase the hardness of the alloy due to the consistency and coherency of the later phase. However, the decrease of hardness is mainly associated with the coarse microstructures, that can be formed due to the phase transformation from metastable β'-Cu4Ti phase to more stable Cu3Ti phase. In the range of experiments, the optimum process is solution treatment at 700°C for 4 h, with subsequent age-hardening at 450°C for 4 h. The electrical conductivity, hardness, tensile strength, and elongation of the Cu-3Ti-2Mg alloy were 15.34 % IACS, 344 HV, 533 MPa, and 12%, respectively.

Opis:
This research work address the fabrication of copper (Cu) matrix composites, reinforced with fly ash (FA) particulates with 3, 6, 9 and 12 wt.% using the powder metallurgy route. The microstructural, physical, electrical, thermal, mechanical and tribological properties of thus fabricated Cu-FA composites have been studied. Optical microstructural characterization of the composites exposed persuasively uniform distribution of FA reinforcement with minimum porosity. The mixed powder SEM images revealed the homogeneous dispersion of fly ash particulates in the copper matrix. The hardness values showed improvement with increase in the weight percentage of FA in the Cu matrix. Electrical conductivity was measured using the four-point probe method at room temperature. Thermal conductivity was measured with a thermal diffusivity analyzer at room temperature. The fly ash addition leads to weakening the conductivity of Cu-FA composites. The tribological properties of Cu-FA composite specimens were investigated using a Pin-on-disc tribo testing machine against an EN81 steel contour disc. The specific wear rate of the composites tended first to decrease, which was attributed mainly to the formation of a mechanically mixed layer on the worn surface. Then it would increase as the FA content increased because of reduction in ductility and brittle oxide cracks associated with adding more FA particulates. It seems that composites with FA percentages below 9wt.% have optimum properties of microstructure, hardness and wear resistance, which is suitable for applications such as electrical sliding contacts, electrical discharge machining and spot welding electrodes.

Opis:
The progressive degradation of soils is a recently increasing environmental problem. The risk of soil degradation may be associated, for example, with landslides, flooding, soil erosion. However, these are relatively rare phenomena compared to the risk of chemical degradation caused by human activity. Given the limited research on the positive effect of miscanthus biochar on soil properties, a study was carried out aimed at determining changes in pH, electrical conductivity, sorption properties, and mobility of selected heavy metals in sandy soil treated with various chemicals. Biochar used in the study was produced at a temperature of 300°C. The addition of biochar to soil generally increased the pH value, regardless of the type of chemical degradation. The study revealed a decrease in the hydrolytic acidity value and, at the same time, no significant changes in the content of alkaline cations and sorption capacity of the biochar-treated soil. The best effect on reducing the mobility of trace elements was achieved by adding biochar to the soil supplemented with acidifying substances. Bearing in mind the current agricultural and environmental problems, there is a need to increase the effectiveness of biochar and to direct its action to improve specific soil properties.

Mixed ionic and electronic conducting K2NiF4-type oxide, Nd2Ni1-xCuxO4+δ (x=0~1) powders were synthesized by solid state reaction technique and solid oxide fuel cells consisting of a Nd2Ni1-xCuxO4+δ cathode, a Ni-YSZ anode and ScSZ as an electrolyte were fabricated. The effect of copper substitution for nickel on the electrical and electrochemical properties was examined. Small amount of copper doping (x=0.2) resulted in the increased electrical conductivity and decreased polarization resistance. It appears that this phenomenon was associated with the high mean valence of nickel and copper and the resulting excess oxygen (δ). It was found that power densities of the cell with the Nd2Ni1-xCuxO4+δ (x=0.1 and 0.2) cathode were higher than that of the cell with theNd2NiO4+δ cathode.

Opis:
Structural, elastic, electronic, magnetic and thermoelectric properties of the Heusler compounds: Zr₂PdAl, Zr₂PdGa, and Zr₂PdIn are performed using generalized gradient approximation with exchange-correlation function of the Perdew-Burke-Ernzerhof. The elastic constants are calculated at P=0 GPa. From the obtained elastic parameters, it is inferred that these compounds, with the Hg₂TiCu-type structure, are elastically stable and ductile in nature. The calculated density of states, magnetic moments and band structure are also given. The band structures of these compounds reveal that all of them have almost half metallic character with the narrow indirect band gap in the minority spin channel that amounts to 0.36, 0.46, and 0.40 eV for Zr₂PdAl, Zr₂PdGa, and Zr₂PdIn, respectively. The total spin magnetic moments (M_{tot}) of the considered compounds are very close to integer value 3, which satisfies a Slater-Pauling type rule for localized magnetic moment systems M_{tot}=Z_{T}-18, where Z_{T}=21 is the number of valence electrons in the primitive cell. The thermoelectric properties of these materials are discussed on the basis of the Seebeck coefficients, electrical and thermal conductivity relative to relaxation time as a function of temperature, at the Fermi level, using the Boltzmann transport theory. After several browse in the literature, the obtained results are the first predictions of the physical properties for the inverse full-Heusler compounds Zr₂PdZ (Z = Al, Ga and In).

Opis:
Modern manufacturing methods of non-ferrous metals, especially aluminum and its alloys, are more and more often based on integrated technologies combining multiple operations in a single process. One of the most popular methods for producing flat components by cold working is twin roll casting technology (TRC). It allows to eliminate from manufacturing the extremely expensive hot rolling operation, as the TRC semi-product (strip) can be directly cold rolled. The results of mechanical and electrical properties and structure examination of strips after casting were presented in the paper. The effect of cold rolling parameters on post-process mechanical properties and structure of sheets was investigated too.
